[[Operating system]]s ported to the architecture include SGI's [[IRIX]], [[Microsoft]]'s [[Windows NT]] (through v4.0), [[Windows CE]], [[Linux]], [[FreeBSD]], [[NetBSD]], [[OpenBSD]], [[Unix|UNIX]] [[System V]], [[SINIX]], [[QNX]], and MIPS Computer Systems' own [[RISC/os]].

In the early 1990s, speculation occurred that MIPS and other powerful [[RISC]] processors would overtake the Intel [[IA-32]] architecture. This was encouraged by the support of the first two versions of [[Microsoft]]'s [[Windows NT]] for [[DEC Alpha|Alpha]], MIPS and [[PowerPC]], and to a lesser extent the [[Clipper architecture]] and [[SPARC]]. However, as Intel quickly released faster versions of their [[Pentium]] class CPUs, Microsoft [[Windows NT]] v4.0 dropped support for anything but IA-32 and Alpha. With [[Silicon Graphics|SGI]]'s decision to transition to the [[Itanium]] and IA-32 architectures in 2007 (following a 2006 Chapter 11 bankruptcy<ref>{{cite news |url=https://www.wsj.com/articles/SB114708367971646497 |title=Silicon Graphics Seeks Chapter 11 As Sales Decline |author=Patrick Fitzgerald|work=[[Wall Street Journal]] |date=6 May 2006 |url-access=subscription}}</ref>) and 2009 acquisition by [[Silicon Graphics International|Rackable Systems, Inc.]], support ended for the MIPS/IRIX consumer market in December, 2013 as originally scheduled. However, a support team still exists for special circumstances and refurbished systems that are still available on a limited basis.<ref>{{cite web |url=http://www.sgi.com/services/support/irix_mips.html |title=End of General Availability for MIPS® IRIX® Products |work= |date=2013}}</ref>

{{Main|Loongson}}

[[Loongson]] is a family of MIPS-compatible microprocessors designed by the [[Chinese Academy of Sciences]]' Institute of Computing Technology (ICT). Independently designed by the Chinese, early models lacked support for four instructions that had been patented by MIPS Technologies.<ref>{{cite web |url=http://www.mdronline.com/mpr/h/2006/0626/202602.html |title=China's Microprocessor Dilemma |publisher=The Linley Group}}</ref> In June 2009, ICT licensed the MIPS32 and MIPS64 architectures from MIPS Technologies.<ref>{{Cite web |url=http://www.mips.com/news-events/newsroom/release-archive-2009/6_15_09.dot |title=China’sChina's Institute of Computing Technology Licenses Industry-Standard MIPS Architectures |access-date=2017-04-21 |url-status=dead |archive-url=https://web.archive.org/web/20110508055843/http://www.mips.com/news-events/newsroom/release-archive-2009/6_15_09.dot |archive-date=2011-05-08}}</ref> Starting in 2006, many companies released Loongson-based computers, including [[nettop]]s and [[netbook]]s designed for low-power use.<ref>{{cite web |url=http://www.linuxfordevices.com/c/a/News/Chinese-150-Linux-miniPC-races-OLPC-to-market/ |title=LinuxDevices article about the Municator |url-status=dead |archive-url=https://archive.is/20121216080125/http://www.linuxfordevices.com/c/a/News/Chinese-150-Linux-miniPC-races-OLPC-to-market/ |archive-date=2012-12-16}}</ref><ref>{{cite web |url=http://www.linuxdevices.com/news/NS2928309621.html |title=''Yeelong'' Specs |publisher=LinuxDevices |date=22 October 2008 |url-status=dead |archive-url=https://archive.is/20121210034609/http://www.linuxfordevices.com/c/a/News/Netbook-runs-Debian-on-Chinamade-CPU/ |archive-date=10 December 2012}}</ref>

In recent years, the Loongson space dedicated chip (1E04/1E0300/1E1000,1F04/1F0300,1J) has been used on 3–5 Beidou navigation satellites.
